The reproducibility of measurements of mean liver stiffness was evaluated in 53 patients who underwent serial MR Elastography. The percent difference in mean liver stiffness on the two examinations averaged 8% - 11% with excellent reproducibility that was independent of the degree of liver stiffness. Similar agreement of MRE measurements was found on the two different GE 1.5T scanners used in this study which included a GE HDx and a GE MR 450 scanner.
